[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. The fitting 1 of the first embodiment will be described. In this specification, the "finding direction" means the surface direction of the facing material in the fitting 1 housed in the opening formed in the wall of the building, and the "prospective direction" means the thickness direction (i.e., the depth direction) of the facing material. The "prospective direction" is also the indoor-outdoor direction. The "found surface" means each surface facing the outdoor side and the indoor side in the fitting 1, and the "prospective surface" means the surface extending in the indoor-outdoor direction in the fitting 1. In the drawings, the outdoor side of the fitting 1 is designated as the outdoor side X1, and the indoor side of the fitting 1 is designated as the indoor side X2. Also, the "lateral direction" of the outer shutter 5 is also referred to as the left-right direction.

[0009] As shown in FIGS. 1 and 2, the building fixture 1 includes a frame body 2 attached to an opening of a building body (not shown), a vertical post 3 (a facing material holding member) disposed within the frame body 2, a FIX portion 4 disposed on the indoor side X2 within the frame body 2 on one side in the left - right direction of the vertical post 3, an outer shutter 5 disposed movably in the left - right direction on the outdoor side X1 within the frame body 2, and a pleated screen door 6 (a retractable screen door) disposed pull - out - ably on the indoor side X2 on the other side in the left - right direction of the vertical post 3 within the frame body 2.

[0010] The frame body 2 is configured by framing an upper frame 21, a lower frame 22, and a pair of left - right vertical frames 23, 24 in a rectangular shape.

[0011] As shown in FIGS. 3 and 4, the upper frame 21 has an upper frame main body 211, an upper frame indoor - side surface cover 212 disposed on the surface of the indoor side X2, and an upper frame indoor - side lower - end cover 213 attached to the lower end of the upper frame indoor - side surface cover 212.

[0012] The upper frame indoor - side surface cover 212 has a FIX - side upper frame indoor - side surface cover 212b (see FIG. 4) formed on the FIX - portion 4 side in the left - right direction, and a shutter - side upper frame indoor - side surface cover 212a (see FIG. 3) disposed with a gap between it and the FIX - side upper frame indoor - side surface cover 212b formed on the outer - shutter 5 side in the left - right direction.

[0014] The upper frame main body 211 has an upper frame outdoor - side groove 211a formed on the outdoor side X1 and opening downward, and an upper frame indoor - side groove 211b formed on the indoor side X2 and opening downward.

[0015] The upper end of the outer sash 5 is positioned in the upper frame outdoor groove 211a on the outdoor side X1 of the upper frame 21. The upper frame outdoor groove 211a guides the lateral movement of the upper end of the outer sash 5.

[0016] The upper frame interior groove 211b has a fixed glass placement groove 211d (see Figure 4) formed on the left-right fixed section 4 side, and a screen door placement groove 211c (see Figure 3) formed on the left-right outer sash 5 side. As shown in Figure 3, a screen door attachment 211e is placed in the screen door placement groove 211c. The screen door placement groove 211c guides the left-right movement of the upper end of the pleated screen door 6 via the screen door attachment 211e. As shown in Figure 4, the upper end of the glass panel 41 of the fixed section 4 is placed in the fixed glass placement groove 211d.

[0017] As shown in Figures 3 and 4, the lower frame 22 includes a lower frame body 221, a lower frame indoor surface cover 222 positioned on the indoor side X2 surface, and a lower frame indoor upper end cover 223 attached to the upper end of the lower frame indoor surface cover 222.

[0018] The lower frame interior surface cover 222 includes a fixed-side lower frame interior surface cover 222b (see Figure 4) formed on the left-right fixed section 4 side, and a sash-side lower frame interior surface cover 222a (see Figure 3) formed on the left-right outer sash 5 side and positioned with a gap between it and the fixed-side lower frame interior surface cover 222b.

[0019] The lower frame indoor upper end cover 223 includes a fixed-side lower frame indoor upper end cover 223b (see Figure 4) formed on the left-right fixed section 4 side, and a sash-side lower frame indoor upper end cover 223a (see Figure 3) formed on the left-right outer sash 5 side and positioned with a gap between it and the fixed-side lower frame indoor upper end cover 223b.

[0020] The lower frame body 221 has a lower frame rail 221a formed on the outdoor side X1 and projecting upward, and a lower frame indoor groove 221b formed on the indoor side X2 and opening upward.

[0021] The lower end of the outer sash 5 is positioned on the lower frame rail 221a on the outdoor side X1 of the lower frame 22. The lower frame rail 221a guides the left-right movement of the lower end of the outer sash 5.

[0022] The lower frame interior groove 221b has a fixed glass placement groove 221d (see Figure 4) formed on the left-right fixed section 4 side, and a screen door placement groove 221c (see Figure 3) formed on the left-right outer sash 5 side. As shown in Figure 3, a screen door attachment 221e is placed in the screen door placement groove 221c. The screen door placement groove 221c guides the left-right movement of the lower end of the pleated screen door 6 via the screen door attachment 221e. As shown in Figure 4, the lower end of the glass panel 41 of the fixed section 4 is placed in the fixed glass placement groove 221d.

[0023] As shown in Figure 5, the vertical frames 23 and 24 each include vertical frame bodies 231 and 241, vertical frame indoor surface covers 232 and 242 positioned on the indoor surface X2, and vertical frame indoor end covers 233 and 243 attached to the left-right inner circumference ends of the vertical frame indoor surface covers 232 and 242.

[0024] As shown in Figure 1, the mullion 3 is positioned extending vertically at an intermediate point in the left-right direction on the indoor side X2 of the frame 2. The opening of the frame 2 is divided left and right by the mullion 3. The mullion 3 partitions the left and right sides of the opening of the frame 2. As a result, on the indoor side X2 of the frame 2, a fixed section 4 is formed on one side in the left-right direction of the frame 2, and an opening 25, which is opened and closed by the outer sash 5, is formed on the other side in the left-right direction of the frame 2. Details of the mounting structure of the mullion 3 will be described later.

[0025] As shown in Figures 1 and 2, the fixed section 4 is constructed by fixing a glass panel 41 (facing material) as a facing material to the mullion 3 and the frame 2 on the left-right side of the mullion 3 within the frame 2, specifically on the fixed section 4 side. The fixed section 4 is a fixed window that cannot be opened or closed. The fixed section 4 is constructed by fitting a glass panel 41 as a facing material into the inner circumference of the portion enclosed by the mullion 3, upper frame 21, lower frame 22, and vertical frame 24 of the frame 2 on the indoor side X2 in the left-right direction relative to the mullion 3 which is located in the middle of the left-right direction of the frame 2.

[0026] As shown in Figures 4 and 5, the outer edge of the glass panel 41 is positioned in the fixed glass placement grooves 31, 211d, 221d, and 241d of the mullion 3 (vertical member), upper frame 21 (upper member), lower frame 22 (lower member), and vertical frame 24 (vertical member), respectively. The outer edge of the glass panel 41 on the side of the mullion 3 in the left-right direction is pressed against the mullion 3 by a glazing strip 35 (glazing strip member), while the upper, lower, and left-right outer edges opposite to the mullion 3 are pressed against fixed side attachments 214, 224, and 244 fixed to the interior side X2 of the upper frame 21, lower frame 22, and vertical frame 24, respectively, by glazing strips 215, 225, and 245. The glazing strips 35, 215, 225, and 245 are attached and fixed in a state where they are hooked and engaged with the mullion 3, upper frame 21, lower frame 22, and vertical frame 24, respectively.

[0027] As shown in Figure 6, the trim strip 35 that presses the outer edge of the glass panel 41 against the mullion 3 presses the airtight material 35a toward the glass panel 41. The airtight material 35a is positioned in contact with the outdoor-facing X1 surface (one side surface) of the end of the glass panel 41 which is placed in the fixed glass placement groove 31 (panel placement groove) of the mullion 3 (panel holding member). In this embodiment, the airtight material 35a is, for example, a dry gasket.

[0028] The trim piece 35 presses the airtight material 35a toward the glass panel 41 on the exterior side X1 of the end of the glass panel 41.

[0029] As shown in Figure 6, the trim strip 35 is formed in a crank shape and extends vertically as shown in Figure 7. As shown in Figure 6, the trim strip 35 is fixed to the inner plate portion 361 of the outdoor portion 36 of the mullion 3 by screws 37 (adjustment fasteners).

[0030] The trim 35 includes an exterior-facing fixing plate 351, a depth-extending plate 352 extending from one end of the exterior-facing fixing plate 351 in the left-right direction to the interior X2, an interior-facing fixing plate 353 extending from the interior X2 end of the exterior-facing fixing plate 351 to one side in the left-right direction, and an airtight material pressing projection 354 that protrudes from the surface of the interior-facing fixing plate 353 to the interior X2 and presses the airtight material 35a against the glass panel 41.

[0031] The fixing plate 351 extending in the direction of the exterior facing of the trim 35 is fixed to the inner plate portion 361 of the exterior portion 36 of the mullion 3 by screws 37. As shown in Figure 7, multiple screws 37 are provided along the longitudinal direction of the trim 35 to fix the trim 35.

[0032] The screw 37 is configured to allow adjustment of the pressing force of the trim 35 toward the glass panel 41, and the trim 35 is fixed to the mullion 3 with the pressing force of the trim 35 toward the glass panel 41 adjusted. By adjusting the degree to which the screw 37 is tightened, the pressing force of the trim 35 toward the glass panel 41 can be adjusted and fixed to the airtight material 35a toward the glass panel 41.

[0033] As shown in Figure 7, the screw 37 is inserted from the outdoor side X1 through the hole 362a in the outer plate portion 362 of the outdoor side portion 36 of the mullion 3, and as shown in Figure 8, it penetrates the inner plate portion 361 of the outdoor side portion 36 of the mullion 3 and the trim 35 in the depth direction to secure them.

[0034] As described above, by providing a structure in which the trim strip 35 is fixed with screws 37, the trim strip 35 can be fixed in a state where it is pressed against the glass panel 41 by the screws 37. Therefore, even if the dimensions of the mullion 3 in the visible direction (width in the left-right direction) are narrow, it is possible to prevent the mullion 3 from coming out of the glass panel 41. In addition, because the trim strip 35 can be pressed against the glass panel 41 by screws 37, the trim strip 35 can be pressed more firmly against the glass panel 41 than in a structure in which the airtight material is inserted and installed after the glass panel is placed in the glass placement groove. Therefore, it is possible to further prevent the mullion 3 from coming out of the glass panel 41.

[0035] As shown in Figure 5, the outer sash 5 is a sash that can be opened and closed by sliding it horizontally within the frame 2 on the outdoor side X1 within the frame 2. The outer sash 5 is configured to open and close an opening 25 formed on the outer sash 5 side in the left-right direction relative to the mullion 3 which is provided in the middle of the frame 2 in the left-right direction. When viewed from the indoor-outdoor direction, the outer sash 5 is in the closed position when it overlaps the opening 25, and is in the open position when it is moved horizontally to the outdoor side X1 of the FIX section 4.

[0036] As shown in Figures 3 and 5, the outer sash 5 is constructed by assembling an upper frame 51, a lower frame 52, a vertical frame 53 positioned on the leading edge side, and a vertical frame 54 positioned on the trailing edge side into a rectangular frame body 50, and then housing a glass panel 55 on the inner circumference of this frame. The upper end of the outer sash 5 is positioned to be movable in the left-right direction in the upper frame outdoor groove 211a of the upper frame 21, and the lower end is engaged with the lower frame rail 221a of the lower frame 22 to be movable in the left-right direction.

[0037] A handle 531 is attached to the vertical frame 53 located on the door edge side, as shown in Figures 1 and 2. The handle 531 is attached to the inner circumference of the vertical frame 53 in the left-right direction, on the interior side X2 of the outer shoji screen 5's surface material 55.

[0038] The details of the mounting structure of the mullion 3 will now be described. As shown in Figures 9 and 10, the mullion 3 is configured to be movable in the left-right direction (lateral direction) by an upper guide portion 61 (guide portion) and a lower guide portion 62 (guide portion) provided on the mullion 3, and is fixed to the frame 2 at a predetermined position in the left-right direction (lateral direction).

[0039] As shown in Figure 9, the upper guide portion 61 is fixed to the upper end of the mullion 3. The upper guide portion 61 is formed by an L-shaped metal fitting. The upper guide portion 61 has a vertically extending portion 611 that is fixed to the upper end of the mullion 3 and extends in the vertical direction, and a horizontally extending portion 612 that extends away from the upper end of the vertically extending portion 611 to one side in the left-right direction.

[0040] The vertically extending portion 611 is formed in a plate shape with thickness in the left-right direction (visible direction). The vertically extending portion 611 has width in the depth direction (indoor-outdoor direction) and extends vertically. The vertically extending portion 611 is connected to and fixed to the upper end of the mullion 3, along the depth surface of the mullion 3.

[0041] The lateral extension portion 612 is formed in a plate shape with thickness in the vertical direction (visible direction). The lateral extension portion 612 has width in the depth direction (indoor / outdoor direction) and extends in the left-right direction. The lateral extension portion 612 extends from the upper end of the vertical extension portion 611 toward the opening 25 in the left-right direction.

[0042] The laterally extending portion 612 is positioned on the left-right opening 25 side of the mullion 3, and is movably positioned in the upper frame indoor groove 211b of the upper frame 21.

[0043] The lateral extension portion 612 has an elongated guide groove 613 that penetrates vertically and extends horizontally. The lateral extension portion 612 is configured to be movable horizontally along the guide groove 613 while temporarily fixed by a screw 612a inserted into the guide groove 613. With the lateral extension portion 612 and the upper frame 21 temporarily fixed by the screw 612a inserted into the guide groove 613, the horizontal position of the mullion 3 is adjusted. Then, with the horizontal position of the lateral extension portion 612 adjusted to a predetermined position, the lateral extension portion 612 and the upper frame 21 are permanently fixed by the screw 612a, and the lateral extension portion 612 and the upper frame 21 are fixed by additional fixing screws 612b and 612c.

[0044] As shown in Figure 10, the lower guide portion 62 is fixed to the lower end of the mullion 3. The lower guide portion 62 is formed by an L-shaped metal fitting. The lower guide portion 62 has a vertically extending portion 621 that is fixed to the lower end of the mullion 3 and extends in the vertical direction, and a horizontally extending portion 622 that extends away from the lower end of the vertically extending portion 621 to one side in the left-right direction.

[0045] The vertically extending portion 621 is formed in a plate shape with thickness in the left-right direction (visible direction). The vertically extending portion 621 has width in the depth direction (indoor-outdoor direction) and extends vertically. The vertically extending portion 621 is connected to and fixed to the lower end of the mullion 3, along the depth surface of the mullion 3.

[0046] The lateral extension portion 622 is formed in a plate shape with thickness in the vertical direction (visible direction). The lateral extension portion 622 has width in the depth direction (indoor / outdoor direction) and extends in the left-right direction. The lateral extension portion 622 extends from the lower end of the vertical extension portion 621 toward the opening 25 in the left-right direction.

[0047] The laterally extending portion 622 is positioned on the left-right opening 25 side of the mullion 3, and is movably positioned in the lower frame indoor groove 221b of the lower frame 22.

[0048] The lateral extension portion 622 has an elongated guide groove 623 that penetrates vertically and extends horizontally. The lateral extension portion 622 is configured to be movable horizontally along the guide groove 623 while temporarily fixed by a screw 622a inserted into the guide groove 623. With the lateral extension portion 622 and the lower frame 22 temporarily fixed by the screw 622a inserted into the guide groove 623, the horizontal position of the mullion 3 is adjusted. Once the horizontal position of the lateral extension portion 622 is adjusted to a predetermined position, the lateral extension portion 622 and the lower frame 22 are permanently fixed by the screw 622a, and the lateral extension portion 622 and the lower frame 22 are fixed by additional fixing screws 622b and 622c.

[0049] Next, the procedure for installing the glass panel 41 into the FIX section 4 and fixing the mullions 3 to the upper frame 21 and lower frame 22 will be described. First, as shown in the upper diagram of Figure 11A, the mullions 3 are temporarily fixed with screws 612a and 622a. Then, as shown in the middle diagram of Figure 11A, they are retracted from the glass panel 41. Finally, as shown in the lower diagram of Figure 11A, the end of the glass panel 41 of the FIX section 4 on the vertical frame 24 side is brought into contact with the FIX-side attachment 244 fixed to the vertical frame 24.

[0050] Next, as shown in the upper diagram of Figure 11B, the mullion 3 is moved towards the glass panel 41 to position it in the left-right direction.

[0051] Then, with the mullion 3 positioned in a predetermined location in the left-right direction, the screws 612a and 622a are permanently fixed as shown in the lower diagram of Figure 11B, and the guide section (upper guide section 61, lower guide section 62) and the frame 2 (upper frame 21, lower frame 22) are fixed with additional fixing screws 612b, 612c, 622b, and 622c.

[0052] Next, as shown in the lower diagram of Figure 11B, the exterior X1 surface of the end of the glass panel 41 on the vertical frame 24 side is pressed with the trim strip 245, and the outer sash 5 is erected on the exterior X1 of the opening 25 of the frame 2. In this way, a fixed section 4 is formed in the joinery 1, and the outer sash 5 can be positioned in the opening 25 of the frame 2.

[0053] As described above, by configuring the mullions 3 to be movable in the left-right direction, the glass panels 41 can be erected with gaps in the left-right direction, thus facilitating the installation of the glass panels 41.

[0054] The mullions 3 described above are configured to be movable in the left-right direction and are fixed to the upper frame 21 and lower frame 22 at predetermined positions in the left-right direction. Therefore, it is necessary to ensure the watertight performance of the mullions 3 at their upper and lower ends, taking into account that the mullions 3 are configured to be movable in the left-right direction. Accordingly, in this embodiment, a watertight structure as shown in Figures 12 to 19 is provided at the upper and lower ends of the mullions 3 to ensure watertight performance between them and the frame 2.

[0055] The watertight structure between the mullion 3 and the frame 2 (upper frame 21, lower frame 22) will now be described. As shown in Figure 12, the upper end of the mullion 3 is positioned midway along the left-right direction of the upper frame 21, and as shown in Figure 16, the lower end is positioned midway along the left-right direction of the lower frame 22.

[0056] In detail, as shown in Figure 12, the upper end of the mullion 3 is positioned in close contact with a watertight component located in the gap between the indoor surface cover 212b of the fixed-side upper frame and the indoor surface cover 212a of the sash-side upper frame, and a watertight component located in the gap between the indoor lower end cover 213b of the fixed-side upper frame and the indoor lower end cover 213a of the sash-side upper frame, in the left-right direction. As shown in Figure 16, the lower end of the mullion 3 is positioned in close contact with a watertight component located in the gap between the indoor surface cover 222b of the fixed-side lower frame and the indoor surface cover 222a of the sash-side lower frame, and a watertight component located in the gap between the indoor upper end cover 223b of the fixed-side lower frame and the indoor upper end cover 223a of the sash-side lower frame, in the left-right direction.

[0057] As shown in Figures 12 to 15, a mullion-side upper watertight member 32 (upper watertight member) is attached to the upper end of the mullion 3. An upper frame-side upper watertight member 71 (upper watertight member) is placed where the upper end of the mullion 3 is positioned on the upper frame 21. The mullion-side upper watertight member 32 is formed in a block shape and is placed in the upper frame indoor side groove 211b of the upper frame 21.

[0058] As shown in Figures 12 to 15, the upper watertight member 71 on the upper frame side is positioned on the vertical frame 24 side in the left-right direction relative to the upper end of the mullion 3. The upper watertight member 71 on the upper frame side has a watertight block 711 that is formed in a block shape and extends in the depth direction. A watertight sealing material 711a is provided on the upper surface of the watertight block 711. A watertight sealing material 711b is provided on the surface of the watertight block 711 that is on the mullion 3 side. A watertight sealing material 711c is provided on the indoor side X2 side surface of the vertical frame 24 side surface of the watertight block 711.

[0059] The upper watertight member 71 on the upper frame side is installed such that the watertight sealing material 711a abuts against the lower surface of the upper frame 21, the watertight sealing material 711b abuts against the mullion 3 and also abuts against the end faces 212c and 213c of the longitudinal ends of the indoor surface cover 212a and the indoor lower end cover 213a of the upper frame on the sash side of the upper frame 21, and the watertight sealing material 711c abuts against the end faces 212d and 213d of the longitudinal ends of the indoor surface cover 212b and the indoor lower end cover 213b of the upper frame on the fixed side of the upper frame 21. This improves the watertight and airtight performance between the upper end of the mullion 3 and the upper frame 21.

[0060] As shown in Figures 16 to 19, a lower watertight member 33 (lower watertight member) is attached to the lower end of the mullion 3. A lower watertight member 72 (lower watertight member) is placed where the lower end of the mullion 3 is positioned on the lower frame 22. The lower watertight member 33 is formed in a block shape and is placed in the lower frame indoor groove 221b of the lower frame 22.

[0061] As shown in Figures 16 to 19, the lower watertight member 72 on the lower frame side is positioned on the vertical frame 24 side in the left-right direction relative to the lower end of the mullion 3. The lower watertight member 72 on the lower frame side has a watertight block 721 that is formed in a block shape and extends in the depth direction. A watertight sealing material 721a is provided on the lower surface of the watertight block 721. A watertight sealing material 721b is provided on the surface of the watertight block 721 that is on the mullion 3 side. A watertight sealing material 721c is provided on the indoor side X2 side surface of the vertical frame 24 side surface of the watertight block 721.

[0062] The lower watertight member 72 on the lower frame side is installed such that the watertight sealing material 721a abuts against the upper surface of the lower frame 22, the watertight sealing material 721b abuts against the mullion 3 and also abuts against the end faces 222c and 223c of the longitudinal ends of the indoor surface cover 222a and the indoor upper end cover 223a of the lower frame on the sash side of the lower frame 22, and the watertight sealing material 721c abuts against the end faces 222d and 223d of the longitudinal ends of the indoor surface cover 222b and the indoor upper end cover 223b of the lower frame on the fixed side of the lower frame 22. This improves the watertight and airtight performance between the upper end of the mullion 3 and the lower frame 22.

[0063] Next, we will explain the structure provided from a security standpoint. As shown in Figure 5, the door 1 of this embodiment is a so-called externally movable type door in which the outer sash 5 is arranged to be movable in the left-right direction on the outdoor side X1 of the FIX section 4. When the outer sash 5 is in the closed position, the vertical frame 54 located on the tail end side of the outer sash 5 is located on the outdoor side X1 of the mullion 3, and when viewed in the indoor-outdoor direction, it is positioned overlapping the mullion 3.

[0064] As shown in Figures 4 and 5, the retaining strips 35, 215, 225, and 245 that press against the outer edge of the glass panel 41 on all four sides of the FIX section 4 are pressed against the indoor side X2 of the FIX glass placement groove 31 of the mullion 3 by the retaining strip 35, and are also pressed against the FIX side attachments 214, 224, and 244 fixed to the indoor side X2 of the upper frame 21, lower frame 22, and vertical frame 24, respectively, by the retaining strips 215, 225, and 245.

[0065] As shown in Figure 20, in the FIX section 4, the trim pieces 35, 215, 225, and 245 are attached to the upper frame 21, lower frame 22, mullion 3, and vertical frame 24. The trim pieces 35, 215, 225, and 245 consist of an upper trim piece 215, a lower trim piece 225, a vertical trim piece 35 on the mullion side (one side vertical trim piece), and a vertical trim piece 245 on the vertical frame side (the other side vertical trim piece), which press against one side of the edge of the glass panel 41.

[0066] The upper glazing edge 215, lower glazing edge 225, mullion-side vertical glazing edge 35, and vertical frame-side vertical glazing edge 245 are arranged along the four sides formed by the upper frame 21, lower frame 22, mullion 3, and vertical frame 24. In this embodiment, the upper glazing edge 215, lower glazing edge 225, mullion-side vertical glazing edge 35, and vertical frame-side vertical glazing edge 245 constitute a four-sided glazing edge that presses against the glass panel 41 on the four sides formed by the upper frame 21, lower frame 22, mullion 3, and vertical frame 24.

[0067] On one side (the side of the vertical post 3) in the left-right direction of the four-sided trim (upper trim 215, lower trim 225, vertical trim 35 on the vertical post side, and vertical trim 245 on the vertical frame side), the longitudinal end of the upper trim 215 is positioned above the longitudinal upper end of the vertical trim 35 on the vertical post side, and the longitudinal end of the lower trim 225 is positioned below the longitudinal lower end of the vertical trim 35 on the vertical post side, thus forming a structure that is known as a horizontally dominant configuration.

[0068] On the other side (vertical frame 24 side) of the four-sided trim (upper trim 215, lower trim 225, vertical trim 35 on the vertical frame side, and vertical trim 245 on the vertical frame side), the longitudinal end of the upper trim 215 is positioned on the inner circumference in the left-right direction of the longitudinal upper end of the vertical trim 245 on the vertical frame side, and the longitudinal end of the lower trim 225 is positioned on the inner circumference in the left-right direction of the longitudinal lower end of the vertical trim 245 on the vertical frame side, thus forming a so-called vertically dominant structure.

[0069] Here, the trim pieces (upper trim piece 215, lower trim piece 225, vertical trim piece 35 on the mullion side, and vertical trim piece 245 on the vertical frame side) are attached to the inner circumference of the mullion 3, upper frame 21, lower frame 22, and vertical frame 24. Therefore, when removing the trim pieces (upper trim piece 215, lower trim piece 225, vertical trim piece 35 on the mullion side, and vertical trim piece 245 on the vertical frame side) attached to the inner circumference of the mullion 3, upper frame 21, lower frame 22, and vertical frame 24, it is necessary to move them further inward from the inner circumference of the mullion 3, upper frame 21, lower frame 22, and vertical frame 24 to remove them.

[0070] In this embodiment, when removing the upper trim 215, lower trim 225, vertical trim 35 on the mullion side (one side vertical trim), and vertical trim 245 on the vertical frame side (the other side vertical trim), first, the vertical trim 35 on the mullion side is removed from the mullion 3. Then, the upper trim 215 is removed from the upper frame 21, and the lower trim 225 is removed from the lower frame 22. After that, the vertical trim 245 on the vertical frame side is removed from the vertical frame 24, thereby allowing the upper trim 215, lower trim 225, vertical trim 35 on the mullion side (one side vertical trim), and vertical trim 245 on the vertical frame side (the other side vertical trim) to be removed.

[0071] In this embodiment, when the vertical trim 35 on the mullion side is not removed from the mullion 3, even if one attempts to move the upper trim 215 and lower trim 225 towards the inner circumference of the mullion 3, upper frame 21, lower frame 22, and vertical frame 24, the vertical trim 35 on the mullion side gets in the way, preventing the removal of the upper trim 215 and lower trim 225. Similarly, even if one attempts to move the vertical trim 245 on the vertical frame side towards the inner circumference of the mullion 3, upper frame 21, lower frame 22, and vertical frame 24, the upper trim 215 and lower trim 225 get in the way, preventing the removal of the vertical trim 245 on the vertical frame side. Therefore, when removing the upper trim 215, lower trim 225, vertical trim 35 on the mullion side, and vertical trim 245 on the vertical frame side, it is necessary to first remove the vertical trim 35 on the mullion side from the mullion 3.

[0072] Here, on the outdoor side X1 of the vertical trim 35 on the mullion side, as shown in Figures 5 and 20, the vertical frame 54 of the outer sash 5 is positioned when the outer sash 5 is in the closed position. Therefore, on one side (the mullion 3 side) in the left-right direction of the four trims (upper trim 215, lower trim 225, vertical trim 35 on the mullion side, and vertical trim 245 on the vertical frame side), when the outer sash 5 is in the closed position, the vertical trim 35 on the mullion side is positioned covered by the vertical frame 54 of the outer sash 5.

[0073] As a result, when the outer sash 5 is in the closed position, the vertical frame 54 of the outer sash 5 covers the vertical trim 35 on the mullion side on the exterior side X1, and the vertical trim 35 on the mullion side cannot be removed from the mullion 3 from the exterior side X1.

[0074] Therefore, by locking the outer sash 5 while it is in the closed position, the vertical trim 35 on the mullion side cannot be removed from the exterior side X1, and consequently, the upper trim 215, lower trim 225, and vertical trim 245 on the vertical frame side cannot be removed either. As a result, the four-sided trim (upper trim 215, lower trim 225, vertical trim 35 on the mullion side, and vertical trim 245 on the vertical frame side) cannot be removed, and the glass panel 41 cannot be removed. Thus, the security performance can be improved.

[0075] Conventionally, when a door 1 is configured as a so-called externally movable type, in which the outer sash 5 is positioned to be movable in the left-right direction on the outdoor side X1 of the fixed section, if both ends of the four-sided trim are configured with a vertically dominant structure, it is possible to move the upper trim 215 and the lower trim 225 inwards in the vertical direction from the outdoor side X1. Also, if both ends of the four-sided trim are configured with a horizontally dominant structure, it is possible to move one vertical trim and the other vertical trim inwards in the left-right direction from the outdoor side X1. For this reason, conventionally, when the trim can be removed from the outdoor side X1, glass fasteners were provided on the glass panel for security reasons.

[0076] In contrast, in this disclosure, one side of the four-sided trim (upper trim 215, lower trim 225, vertical trim 35 on the mullion side, and vertical trim 245 on the vertical frame side) is configured with a so-called horizontally dominant structure, and the other side of the four-sided trim (upper trim 215, lower trim 225, vertical trim 35 on the mullion side, and vertical trim 245 on the vertical frame side) is configured with a so-called vertically dominant structure. Therefore, in the four-sided trim, the vertical trim (vertical trim 35) in the part configured with the so-called horizontally dominant structure must be removed first before the other trims can be removed. Furthermore, when the outer sash 5 is closed and locked, on the exterior side X1, the vertical frame 54 of the outer sash 5 covers the vertical trim 35 on the mullion side, making it impossible to remove the vertical trim 35 on the mullion side, thus improving security performance.

[0077] According to the first embodiment, the following effects are achieved. The joinery 1 of this embodiment is attached to the upper frame 21, lower frame 22, mullion 3 and vertical frame 24 and includes an upper pressing edge 215, a lower pressing edge 225, a mullion-side vertical pressing edge 35 and a vertical frame-side vertical pressing edge 245 that press against one side of the end of the glass panel 41. On one side in the left-right direction, the longitudinal end of the upper pressing edge 215 is positioned above the longitudinal upper end of the mullion-side vertical pressing edge 35, and the longitudinal end of the lower pressing edge 225 is positioned below the longitudinal lower end of the mullion-side vertical pressing edge 35. On the other side in the left-right direction, the longitudinal end of the upper pressing edge 215 is positioned on the inner circumference of the longitudinal upper end of the vertical frame-side vertical pressing edge 245, and the longitudinal end of the lower pressing edge 225 is positioned on the inner circumference of the longitudinal lower end of the other side vertical pressing edge 245.

[0078] As a result, the upper and lower trims 215 and 225 cannot be removed unless the vertical trim 35 on the mullion side is removed from the mullion 3, and therefore the glass panel 41 cannot be removed. Thus, by making the vertical trim 35 on the mullion side in a structure that cannot be removed from the mullion 3, it is possible to prevent the removal of the glass panel 41 and improve security performance.

[0079] Furthermore, in this embodiment, the vertical trim 35 on the mullion side is positioned so that it is covered by the vertical frame 54 of the outer sash 5. As a result, the vertical trim 35 on the mullion side is covered by the vertical frame 54 of the outer sash 5 and cannot be removed. Therefore, the security performance can be improved.

[0080] Next, a second embodiment will be described. For points not described in the second embodiment, the description of the first embodiment can be referenced. In the second embodiment, components similar to those in the first embodiment are given the same reference numerals as in the first embodiment, and their descriptions are omitted.

[0081] In the second embodiment, the glazing bead of the FIX section 4 is a three-sided glazing bead, as shown in Figure 21, whereas the glazing bead of the FIX section 4 in the first embodiment is a four-sided glazing bead. In the second embodiment, the vertical frame 24 and the vertical frame-side vertical glazing bead 245 shown in Figure 20 in the first embodiment are not provided. The upper glazing bead 215, lower glazing bead 225, and vertical glazing bead 35 of the second embodiment constitute a three-sided glazing bead that presses against the glass panel 41 on three sides formed by the upper frame 21, lower frame 22, and mullion 3.

[0082] On one side (the side of the vertical post 3) of the three-sided trim (upper trim 215, lower trim 225, and vertical trim 35 on the vertical post side), the longitudinal end of the upper trim 215 is positioned above the longitudinal upper end of the vertical trim 35 on the vertical post side, and the longitudinal end of the lower trim 225 is positioned below the longitudinal lower end of the vertical trim 35 on the vertical post side, thus forming a structure that is known as a horizontally dominant configuration.

[0083] On the other side in the left-right direction of the three-sided trim (upper trim 215, lower trim 225, and vertical trim 35 on the vertical side), vertical trim is not provided at the other end of the upper trim 215 and lower trim 225 in the left-right direction, and the end is left open.

[0084] In the second embodiment, where the upper trim 215, lower trim 225, and vertical trim 35 on the mullion side constitute a three-sided trim, similar to the first embodiment, the other trims cannot be removed unless the vertical trim (vertical trim 35) in the portion configured in a so-called horizontally dominant structure is removed first. Also, similar to the first embodiment, when the outer sash 5 is closed and locked, on the exterior side X1, the vertical frame 54 of the outer sash 5 covers the vertical trim 35 on the mullion side, preventing the removal of the vertical trim 35, thus improving security performance.

[0085] According to the second embodiment, the following effects are achieved. The joinery 1 of this embodiment is attached to the upper frame 21, the lower frame 22, and the mullion 3 and includes an upper pressing edge 215, a lower pressing edge 225, and a mullion-side vertical pressing edge 35 that press against one side of the end of the glass panel 41. The upper pressing edge 215, the lower pressing edge 225, and the mullion-side vertical pressing edge 35 are arranged along the three sides formed by the upper frame 21, the lower frame 22, and the mullion 3. On one side in the left-right direction, the longitudinal end of the upper pressing edge 215 is positioned above the longitudinal upper end of the mullion-side vertical pressing edge 35, and the longitudinal end of the lower pressing edge 225 is positioned below the longitudinal lower end of the mullion-side vertical pressing edge 35.

[0086] As a result, similar to the first embodiment, the upper and lower trims 215 and 225 cannot be removed unless the vertical trim 35 on the mullion side is removed from the mullion 3, and therefore the glass panel 41 cannot be removed. Thus, by making the vertical trim 35 on the mullion side inremovable from the mullion 3, removal of the glass panel 41 can be prevented, and security performance can be improved.

[0087] While a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the embodiment described above and can be modified as appropriate.
